摘要： Among the recording/reproducing apparatus such as digital VCR, recording/reproducing and converting may be conducted using digital interface even if there are difference in the type of audio sampling and video compression. DV bus data is provided at digital I/F circuit 2, and A/V separator 101 separates the data into audio and video. The separated audio data undergoes the de-interleave processing at de-interleave instrument 102, and the rate conversion at rate converter 103. The rate- converted audio data undergoes the frame sequence processing and interleave processing at interleave instrument 104. While, the video data is delayed at delay memory 105, where the delay in the audio data processing is taken into account. These audio data and video data are multiplexed at A/V multiplexer 106 to output the DV bus data 3, which is recorded after having been applied with due processing for recording.

摘要： Disclosed is a digital signal recording and reproducing device for recording and reproducing a digital video signal. High efficiency encoding means (109) encodes a digital video signal at a high efficiency, and recording means (123, 124, 125) executes a predetermined encoding process for recording on the video data encoded at a high efficiency and records the video data obtained after the encoding process on a recording medium (126). On the other hand, reproducing means (127, 128, 129) reproduces the video data recorded on the recording medium (126), executes a predetermined reproduced data processing for reproduction on reproduced video data and then outputs the video data obtained after the reproduced data processing. Delay means (137a, 137b) delays the video data outputted from the high efficiency encoding means (109) by a delay time of a total of a delay time of the video data relevant to the processing of the recording means (123, 124, 125) and a delay time of the video data relevant to the processing of the reproducing means (127, 128, 129), and outputs delayed video data, and selecting means (141) selectively switches over between the video data outputted from the delay means (137a, 137b) and the video data outputted from the reproducing means (127, 128, 129), and outputs selected one of the two video data.
